WLAN telephony 3, also known as Voice over WLAN (VoWLAN) or Wi-Fi calling, is a technology that allows users to make and receive phone calls over a wireless local area network (WLAN) using a compatible mobile device. This technology enables users to make calls in areas with poor cellular coverage by utilizing a Wi-Fi network for voice communication. WLAN telephony 3 also supports seamless handover between Wi-Fi and cellular networks, providing a more reliable and consistent calling experience for users. Additionally, it can help reduce roaming charges for international calls by utilizing Wi-Fi networks for communication. **

Internet telephony, also known as Voice over Internet Protocol (VoIP), is a technology that allows users to make voice calls over the internet instead of traditional phone lines. This can be done using a computer, a special VoIP phone, or a smartphone app. Internet fax, on the other hand, is a method of sending and receiving faxes using the internet instead of a traditional fax machine. It allows users to send and receive faxes as email attachments or through a web-based interface, eliminating the need for a physical fax machine and phone line. Both internet telephony and internet fax offer cost savings and convenience compared to traditional methods. **

Yes, mobile phone telephony can work over 4G. 4G technology, also known as LTE (Long-Term Evolution), supports both data and voice communication, allowing users to make phone calls over the 4G network. This technology is commonly referred to as VoLTE (Voice over LTE), and it provides higher quality voice calls and faster call setup times compared to traditional 2G and 3G networks. As a result, many mobile carriers have adopted VoLTE to provide a seamless and improved telephony experience for their customers over 4G networks. **
